SPECIFICATION forming part of Letters Patent No. l701,7'39, dated J une 3, 1902.

To @ZZ whom 't may concern:

Be it known that I, ELEAZER KEMPSHALL, a citizen of the United States, residingin Boston, in the county of Suffolk and Sta-te of Mas. sachusetts, have invented certain new and useful Improvements in Golf-Balls, of which the following is a specification.

This invention relates to playing-balls and its object is to produce a ball having strength, fiying power, and other qualities Which render it especially desirable for use in the game of golf.

In the accompanying drawings, Figure l is a part-sectional View showing my improved ball, and Fig. 2 is a sectional View of the last stage in the process of manufacture thereof.

In the views similar parts are designated by similar characters of reference.

For the filling Iprefer to use a gutta-percha or other hard center piece 1, inclosed in a soft-rubber envelop 2, and upon this filling I apply a spherical layer 3, of gatta-percha, lined with fabric 4, outside of which I place a second layer 5, of gutta-percha, lined with fabric 6. The fabric lining 4 is preferably cemented to the rubber 2. For the casingof the ball I use a thin layer of celluloid 7, lined with fabric 8.

The inner layer of fabric-lined gutta-percha may be applied in the formof hemisphericall segments welded at A, and the outerlayer'of` fabric-lined gutta-percha may be similarly applied, the weld being indicated at B andcrossing the weld A at riglitangles, so that, the body of one layer strengthens the weld of' the other layer. The celluloid and fabric,4 casing may be applied in the form of tele-3` scoping or overlapping cups, the lapping of the fabric being indicated at CE The celluloid penetrates the meshes of the fabric, so that the lap forms a substantial joint, While the entire lining 8 of the `celluloid casing forms a reinforcement for the weld B of the outer gutta-percha layer. The body of the latter also reinforces the joint C of the casing D.

The final stage in the process of making the ball is indicated in Fig. 2, in which the same is shown as being compressed in heating-dies 9 and l0, whereby the celluloid segments are Welded togetherand compressed upon the inner shell layers and the ball is given its final serial 110.104,31?. .(No man.)

V form, the pressure of the dies being maintained while the shell cools and hardens. The inner shellllayers 3 and 5 may be previously applied in a similar manner.

Owing to the presence of the several layers of fabric both the gutta-percha and celluloid components of the general shell are strengthened, so that the ball possesses phenomenal durability. By the use of celluloid for the surface or cover of the ball great advantage is gained in its flying power and otherwise. The fabric also serves to deadenthe ball sufficiently to make it excellent for putting without appreciably decreasing the flying power or springiness of the ball when given a hard blow. I regard the dividing of the gut-ta-percha-shell component into two layers by the fabric lining 6 as a feature of great value.

Having described my invention, I claim- 1. A playing ball comprising a rubber Vsphere, a layer of gutta-percha thereon, a layer -of fabric-lined gutta-percha upon said first layer, and a casing of fabric-lined celluloid upon said second gutta-percha layer.

Y' 2.`A playing-ball comprising a rubber sphere, a layer of gutta-percha thereon, a layer of fabric-lined gutta-percha upon said first jlayer, anda'casing of fabric-lined celluloid upon said second gutta-percha layer; said 'gutta-percha and celluloid layers holding said celluloid sphereunder compression.

3. A playing-ball comprising a hard center piece,"a rubber sphere thereon, a fabric-lined 'gutta-percha layer upon said sphere, a second fabric-lined'gutta-percha layer upon said first layer, and a fabric-lined celluloid layer upon saidl second layer.'

v 4. A playing-ball comprising a hard center piece, a rubber sphere thereon, a fabric-lined gutta-perchal layer'upon said sphere, a second fabric-lined gutta-percha layer upon said rst layer, and a fabric-lined celluloid layer upon said second layer, each of said gutta-percha layers consisting of welded hemispherical segr' ments. f

5. A playing-ball comprising a hardcenter piece, a rubber sphere thereon, a fabric-lined gutta-percha layer upon said sphere, a second fabric-li ned gu tta-percha layer upon said first layer, and a fabric-lined celluloid layer upon said second layer; each of said gutta-percha layers consisting of welded hemispherical segments, and the Welds of said segments crossing each other, so that the body of one layer reinforces the weld of the other.

b. A playing-ball comprising a hard center piece, a rubber sphere thereon, a, fabric-lined gutta-perchzt layer upon said sphere, a second fabric-lined gutta-percha layer upon said rst layer, and a fabric-lined celluloid layer upon said second layer; each of said gutter-perche layers consisting of Welded hemispherical segments, the Welds of said segments crossing each other, so that the body of one layer reinforces the Weld of the other; and said celluloid easing consisting of telescoped hemispherical cups welded upon said second gutteperclm layer.

7. A playing-ball comprising a hard center percha layer; the joint or Weld of said casing 3o running crosswise of the weld in said second gutta-perchn layer.
